UNITED STATES FRANK PARIZEK, or CHICAGO, ILLINOIS LEAK-PREVENTION DEVICE FOR VENTS Application filed March 24, 1930. Serial No. 438,527.

My invention relates to means for protecting vent openings such as are used for permitting air circulation to the interior of the walls of the building.

As an example of the types of structures used in which this invention is applicable, in certain parts of the United States for 8X ample in Florida provisions are usually made in the side walls or roofs of the build- 10 ings to permit the outside air to pass through the outer wall to the space between the outer and innerwalls for the purpose of setting up air circulation that will prevent the gathering of moisture on the inner wall and the resultant damage to the decoration thereof. Also in many instances it is desirable to establish vent openings through the entire wall as in the case of the roof of a building whereby to provide air circulation from the exterior to the interior of the building. In order toaccomplish this, there are usually set a number of tile generally hollow and cylindrical in form.

These tile extend through the outer wall of the building and are sloped downwardly toward the exterior so as to normally permit drainage to the outside of the building in case of rain. However, if a rain is accompanied by a heavy wind as is not uncommon,

30 the vent tile will permit the rain to be driven through them to the interior of the building,

and this moisture getting inside of the outer wall is very liable to destroy fine decorations of the inner walls or ceilings and occasion a considerable loss.

This invention has for its principal purpose the provision of a' device which when attached to the tile will prevent driving force of the wind from forcing the water upwardly through the tile to the interior of the building.

My invention also contemplates as a more specific object the provision of a device of this character which may be readily attached to the tile after they are mounted in the building and adjusted so as to properly cooperate therewith.

I will describe one form which the invention may take by reference to the accompanying drawings wherein the preferred form of the invention is disclosed. It is to be understood,- however that this disclosure is illustrative only and is not to be taken as limiting the invention except in so far as it is limited by theclaims.

' In the drawings- Fig. 'l-is a vertical section showing my invent-ion as applied to a tile mounted in the side wall of a building; 7

Fig. 2 is a top plan View partly in section of a tile having my invention applied thereto; and

Fig.3 is a perspective view of the cap element of my invention.

Referring now in detail to the drawings, in Fig. 1 I show in section an outer wall 5 of av building which may be a stucco or other type of wall of a house andan inner wall 6 which is usually a plastered wall or one of a similar nature leaving an air space 7 between the two walls. The climatic conditions are such as to make it advisable to provide venting means for this air space, and for this reason most of the buildings are built with vent pipessuch as the tile 8 inserted in the outer wall either in the vertical wall or in the roof. These tile are sloped downwardly toward the exterior of the building as shown in Fig. 1 in order that they may drain properly. so

However, if the wind is blowing against the open ends of these tile members with a rain falling, a great deal of water will be forced inside the walls through these tile members. In order to'prevent this, I provide an attachment consisting of the cap member 9 which is flanged as shown at 10, 11. and 12 to engage the front of the tile and which has the outer wall 13 spacedfrom the supporting flange portions. to provide an opening extending from top to bottom through the cap. The side webs 14 and 15 serve to connect the outer plate with the flange portion. This element is mounted on a the end of the tile by means of a spring clip '16 which is substantially U-shaped having the legs bent over as indicated at 17 and 18 to form hooks adapted to snap over the inner end of the tile member 8 in the manner shown 1 x in Fig. 1. This spring clip is then connected by means of the bolt 19 to the member 9, the bolt being screw-threaded into the spring clip 16 to permit adjustment in the length of the attachment to accommodate different lengths of tile. A suitable nut such as indicated at 20 serves to hold the cap 9 in place.

The construction of the legs of the U- shaped member 16 makes it possible to obtain a spring action from them which insures holding the cap 9 tightly in place in spite of any expansion or contraction which might tend to loosen the same.

Now in ase a wind is blowing toward the open mouth of the tile while it is true a certain amount of water will find its way into the interior of the cap 9, the water will be prevented from going up into the tile 8 since the direction of the entering air must be changed, and bring heavier than air will be thrown oti" and passed outwardly through the cap 9. Moreover, the position of the cap prevents the direct force of the wind from striking the open end of the tile.

From the above description it is thought that the construction and advantages of this invention will be clear to those skilled in this art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An attachment for vent tiles comprising a securing member readily attachable to the tile, a bafiie member extending across the outer end of the tile whereby to prevent straight line passage of air into the tile, and means connecting said securing member and baiile member.

2. in attachment for ent tiles comprising a securing member readily attachable to the tile, a. battle member extending across the outer end of the tile whereby to prevent straight line passage of air into the tile, and means connecting said securing member and battle member, said securing member being yieldablc to allow for contraction and expansion of the tile.

:3. An attachment for vent tiles con'iprising a securing member readily attachable to the inner end of the tile, a batiie member extending across the outer end of the tile whereby to prevent straight line passage of air into the tile, and means connecting said securing member and bafile member.

+1. Means for bathing vent pipes for houses comprising a cap member having means for positioning the same at the outer end of the pipe and having a closed end spaced from the end of the pipe, said member being provided with openings providing a passage transversely across the end of the pipe between the pipe and said closed end, and means for attaching the cap member to the pipe.

Means for bafiiing vent pipes for houses ctanprising a cap member having means for end of the pipe, said member being provided with openings providing a passage transversely across the end of the pipe between the pipe and said closed end, and means for at taching the cap member to the pipe, said last named means including a securing member insertible into the pipe from said outer end.

6. Means for bafiling vent pipes for houses comprising a cap member having means for positioning the same at the outer end of the pipe and having a closed end spaced from the end .of the pipe, said member being provided with openings providing a passage transversely across the end of the pipe bc tween the pipe and said closed end, and means for attaching the cap member to the pipe, said last named means including a securing member insertible into the pipe from said outer end and having hook means for detachably engaging said pipe.

7. Means for baflling vent pipes for houses comprising a cap member having means for positioning the same at the outer end of the pipe and having a closed end spaced from the end of the pipe, said member being provided with openings providing a passage transversely across the end of the pipe between the pipe and said closed end, and means for ataching the cap member to the pipe, said last named means including a securing member insertible into the pipe from said outer end, and an adjustable connection between said cap member and securing member.

8. Means for bafiling vent pipes for houses comprising a cap member having means for positioning the same at the outer end of the pipe and having a closed end spaced from the end of the pipe, said member being provided with openings providing a passage transversely across the end of the pipe between the pipe and said closed end, and means for attaching the cap member to the pipe, said last named means including a U-shaped securing member having hooks on the extremities oi the legs thereoi for hooking over the inner end of the pipe, and means connecting said cap member to said U-shaped member.

In witness whereof, I hereunto subscribe my name this 3rd day of \l'arch, A. D. 19 ,0.
